你可以用Ext.apply或Ext.applyIf這樣做。

var userModel = Ext.create('Balaee.model.sn.UserModel',{}), 
    proxy = userModel.getProxy(); 

Ext.apply(proxy.api, { 
    create : '/controller/new', 
    read : '/controller/load', 
    update : '/controller/update', 
    destroy : '/controller/destroy_action' 
});
